HEATER.

Specification of Letters Patent.

Patented Oct. 8,1912.

To all whom it may concern:

Be it known that I, WILLIAM H. Jones, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Heaters, of which the following is a description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to a combined househeating and water-heating apparatus, comprising a main heater having circulating connections with the radiating apparatus of a house-heating system and a supplemental or auxiliary heater having its heating chamber arranged in heat-conductive relation with the heating chamber or passages of such main heater, and connected with a hot water tank to maintain a supply of hot water which may be piped to such fixture as desired.

The object of my invention is to provide a simple and economical arrangement of the two heaters whereby the main heater will, under ordinary conditions, serve to supply heat both to the house-heating system and the connections associated with the hot water tank, but in which if desired the auxiliary heater may be used to increase the amount of heat supplied to such systems, and in which, also, the auxiliary or tank heater may be used alone for the purpose of keeping up a supply of hot water in the tank, and at the same time, if desired, maintaining a circulation of mildly heated water through the circulating system associated with the main heater.

I have illustrated one form or embodiment of my invention in the accompanying drawings, in which- Figure 1 represents a vertical section of my heater on the line 11 of Fig. 2, the tank and pipe connections being shown in elevation; Fig. 2 a horizontal section of the heater on the line 2-2 of Fig. 1; and Figs. 3 and 4 fragmentary sections of a modified construction. a

The main heater of my apparatus as'illustrated is provided with the usual ash-pit, grate, and a combustion chamber A, in the present instance approximately square in cross-section, surrounded by a water chamber or jacket B, which atthe top is connected with the outlet pipe C. leading to the radiating apparatus D in the building which is heated by it, and at the bottom is con- I ber B of the main heater.

nected with the return pipe E through which the cooled water is conveyed back after passing through such radiating apparatus. The auxiliary or tank heater is likewise provided with an ash-pit, grate and a combustion chamber F, in the present instance of an oblong shape in cross-section, surrounded by a water jacket G, one side of which is in heat-conductive relation to the water cham- On the opposite side of the main heater from the tank heater I preferably employ, for the purpose of obtaining a greater amount of heating space for heating the water in the tank H, a water chamber I, this water chamber and the water jacket of the tank heater being respectively connected at their top portions with the branches J and K of the hot water outlet L leading to the tank. and at their lower portions connected with the branches M and N of the return or cold water pipe 0, it being understood that the tank is provided with the usual service connections to mains furnishing a supply of water under pressure, and also with pipes for distributing the hot water to whatever fixtures it is designed to furnish with hot water.

It will be noted that whether the main heater be used alone or the tank heater alone, the amount of water-heating space communicating with the tank is practically the same, the space being equalized or balanced on opposite sides of the heater which at the time is used, in either case.

As shown in Fig. 1, the main heater, the tank heater on one side of it, and the water heating chamber on the other, are arranged to together form a compact rectangular structure. The outer top wall of the water chamber G, and the outer top wall of the water chamber I in the present instance, and preferably, extend inwardly over a portion of the outer top wall of the water jacket B of the main heater for the purpose of obtaining a greater heating effect therefrom. If desired, the water chambers G and I may extend, both at the back of the main heater and over its top. to communicate with each other, (see Figs. 3 and 4) the back and top walls of such chambers in such case forming respectively single continuous walls at the back and over the top of the main heater, and the outlet pipe C of the main heater being carried through the outer water chambertothc \vater chamberli.

A cut-oil valve P is interposed in the out let pipe C of the main heater, and a drain cock Q is provided in the return pipe E for draining the water from the chamber B andv communicating passages when desired.

lit is evident that in moderate weather the main heater of a combined house-heating and water-heating apparatus constructed as above described may be used to both heat a from the radiating apparatus of the househeating system associated with the main heater. the heat of the water in the chamber G of the tank heater in such case inducing a secondary circulation in the passages of the house-heating system. W hen the valve P is closed the water in the chamber or water jacket B is dead, and practically serves as a non-conductor, preventing loss of heat through the wall separating such chamber from the chamber G of the tank heater.

By the use oftwo heaters of difi'erent ca pacities, combined and associated as described, I obtain a heating apparatus having 0 a wider range of capacity and utility than any heretofore known.

.While I have shown my combined househeating and water-heating apparatus as constructed with a single sheet or thickness of meal intermediate the water chambers B an walls of the tank heater and the chamber ll being riveted to the front and rear walls of the main heater, it will be understood that the tank heater may be constructed with an independent inside wall making a complete.

inclosure or the water jacket or chamber Gr, and the water chamber ll constructed 111 like manner, and the separate portions bolted or otherwise secured together in contact in heat-conductive relation in any suitable manner. It will also bet-understood that while I have shown and described a main heater adapted for heating a building through the circulation of hotwater, myinvention may be applied to a heater having a boiler and adapted to operate by means of the circulation of steam through proper radiating apparatus. It will be also understood that while for convenience in describing and claiming my invention l have described the main heater as connected to house-heating apparatus, and the auxiliary heater as connected to a hot water tank, the particular kind ofradiating apparatus or purpose for which it is employed is immaterial, and the-outlet and'return connections of what l have termed the tank heater may G. and B and T," the front and rear,

be connected to radiating apparatus of any suitable kind for any purpose to which it may be adapted.
